Waste Stream Targeted:  Sodium Cyanide 


  • This small jewelry manufacturer uses sodium cyanide in production of jewelry, but does not have adequate disposal practices for spent solution.  MAMTC engineer assisted business in implementing an economical and environmentally acceptable solution for disposal.

Waste Reduction Activities 

  • The MAMTC engineer determined that the small amounts of sodium cyanide used in the jewelry manufacturing process did not justify or require off-site disposal on a monthly basis.  Monthly off- site disposal would have been cost-prohibitive to the business because of its rural location and the cost would have significantly affected their bottom line.  A plan was developed to store spent sodium cyanide in an acceptable container until the container was full.  At the same time the owner agreed to escrow money on a monthly basis into a fund earmarked to cover the cost of off- site disposal as needed.  This allowed the owner to afford the off-site disposal when required.
